Description

Technical Field

[0001] This invention belongs to the field of chain stopper technology, specifically a chain stopper for ships. Background Technology

[0002] When a ship is anchored at an anchorage, it is usually anchored to the seabed with an anchor chain, and then the ship is towed by the anchor chain. When sailing or when the anchor chain is not needed, the anchor winch is often used to drive the anchor chain wheel in the reverse direction. Finally, the anchor winch is braked, and the anchor chain is locked by the chain catcher and stored in the anchor chain bin. When dropping anchor, the anchor winch drives the anchor chain wheel in the forward direction, and the anchor chain is lowered into the sea.

[0003] Existing technologies also offer some solutions. For example, a Chinese patent application (CN216783773U) discloses a chain catcher base. This base is installed on a ship, which includes a deck and a reinforcing structure at the lower end of the deck. The chain catcher base includes a base body, which is positioned on the deck and corresponds to the reinforcing structure. The base body supports the chain catcher, which has a first connecting hole. During the small-section assembly stage of the ship, the base body is installed on the deck at the position corresponding to the reinforcing structure. Then, the chain catcher is installed on the chain catcher base. The first and second connecting holes are connected by a connector, preventing misalignment between the chain catcher and the reinforcing structure below the deck, and avoiding on-site cutting and repeated welding, thus effectively improving installation efficiency.

[0004] The above technical solution avoids the misalignment of the chain catcher and the reinforcement structure below the deck. However, there are still other problems in actual use. For example, when using the chain catcher to lock the anchor chain, a single guillotine or clamp is currently used to lock the anchor chain. In this case, when subjected to the impact of wind and waves, the huge tensile force borne by the single guillotine or clamp may cause the anchor chain to detach.

[0005] Therefore, the present invention provides a chain stop for ships. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a chain catcher for ships, including a hull frame, a chain catcher base mounted on the surface of the hull frame, a guide sprocket rotatably disposed inside the chain catcher base, a guide sprocket groove formed on the surface of the guide sprocket, an anchor chain disposed on the surface of the guide sprocket, a fixed frame mounted above the chain catcher base, a rotating horizontal shaft rotatably disposed on the inner side of the fixed frame, the end of the rotating horizontal shaft being connected to the output end of a motor, and a knife block holder fixedly mounted on the outer circumferential surface of the rotating horizontal shaft.

[0008] Preferably, a fitting plate is installed at the end of the gate holder away from the horizontal axis of rotation. Multiple locking rods are provided on the lower end face of the fitting plate. These locking rods are used to engage with the horizontal link gaps of the anchor chain and engage the anchor chain. An adjustment unit is provided on the lower end face of the fitting plate to adjust the position of the locking rods. During operation, when it is necessary to brake the anchor chain, the control motor drives the horizontal axis of rotation. The horizontal axis of rotation drives the gate holder to rotate towards the side closer to the anchor chain. The gate holder then causes the fitting plate to press against the surface of the anchor chain. Through the adjustment unit, the locking rods at different positions can be adjusted to engage with the horizontal link gaps of the anchor chain, and the anchor chain is fixed by the locking rods at different positions. Compared to the huge tensile force originally borne by a single gate or clamping block, this force is distributed to multiple support points, reducing the load on individual components.

[0009] Preferably, the adjustment unit includes an L-shaped support frame, an electric push rod is installed on the side wall of the L-shaped support frame, a rectangular block is fixedly installed on the telescopic end of the electric push rod, the rectangular block is slidably disposed on the lower end face of the bonding plate, and the locking rod is installed on the lower end face of the rectangular block. During operation, when the gate holder rotates towards the side closer to the anchor chain and engages with the horizontal chain link gap of the anchor chain, if the locking rod fails to fully engage with the horizontal chain link gap of the anchor chain, the telescopic end of the electric push rod on the side wall of the L-shaped support frame is moved, causing the telescopic end of the electric push rod to drive the rectangular block and the locking rod to move until the locking rod engages with the corresponding horizontal chain link gap of the anchor chain. This design can precisely control the gap between the locking rod and the anchor chain. When the anchor chain becomes longer due to stretching or there are differences in the chain link size, it is not necessary to replace the entire device; only the position of the locking rod needs to be adjusted to regain a tight fit and ensure effective locking.

[0010] Preferably, an L-shaped support shaft is installed on the lower end face of the rectangular block, and the locking rod is rotatably disposed inside the L-shaped support shaft. A circular groove adapted to the locking rod is opened on the surface of the rectangular block. During operation, when the electric push rod controls the movement of the rectangular block and the locking rod, the locking rod can also be controlled to rotate on the surface of the L-shaped support shaft, so that the angle of the locking rod can be adjusted. This allows the locking rod to better engage in the gaps of different horizontal chain links of the anchor chain, making the operation more convenient and facilitating the locking of the anchor chain.

[0011] Preferably, the clamping rod is provided with a ball bearing on the side near the anchor chain, and the end of the clamping rod is provided with a limiting bracket adapted to the ball bearing. During operation, when braking the anchor chain, the guillotine can be moved closer to the anchor chain first, so that the guillotine drives the clamping rod and the ball bearing at its bottom to contact the anchor chain first. At this time, the ball bearing can buffer and decelerate the anchor chain that is sliding at high speed. Then, the clamping rod completes the final locking by the above operation. This staged braking method can effectively avoid damage to the equipment or anchor chain due to excessive jerking force in emergency situations, such as when the anchor winch brake fails.

[0012] Preferably, a gear is installed at the end of the rotating horizontal shaft, and a toothed plate is slidably arranged inside the chain stop base. The toothed plate and the gear are meshed together. A connecting frame is installed at the end of the toothed plate, and a locking pin is provided at the end of the connecting frame away from the toothed plate. During operation, when the rotating horizontal shaft drives the gate holder to rotate towards the side closer to the anchor chain, the rotating horizontal shaft will simultaneously drive the gear at its end to rotate. Since the gear and the toothed plate are meshed together, the gear will drive the toothed plate to move, and the toothed plate will drive the connecting frame to move towards the side closer to the anchor chain. The connecting frame will drive the locking pin to further lock into the gap of the vertical chain link of the anchor chain. With this design, the locking rod can lock the horizontal chain link, and the locking pin can lock the vertical chain link, which plays a secondary safety role. This dispersed force reduces the pressure at each contact point, so that the anchor chain can be braked more smoothly and reliably, reducing the risk of damage to the anchor chain or the chain stop itself due to stress concentration under huge impact force.

[0013] Preferably, the base of the chain stopper has a groove inside that matches the toothed plate, and the diameter of the locking pin is smaller than the length of the gap between the anchor chain links.

[0014] Preferably, a connecting support is installed on the upper end face of the knife gate holder, and a ratchet is installed on the side of the connecting support away from the knife gate holder. A slot is formed on the surface of the chain stopper base, and an engaging unit is provided inside the slot. The engaging unit is used to cooperate with the ratchet and fix the knife gate holder. During operation, when the knife gate holder rotates towards the side closer to the anchor chain, the knife gate holder will simultaneously drive the connecting support to rotate. The connecting support will drive the ratchet to move towards the inside of the slot. Then, the ratchet will cooperate with the engaging unit inside the slot, so that the engaging unit locks the ratchet. This can further improve the stability of the knife gate holder and ensure high safety.

[0015] Preferably, the engaging unit includes a ratchet, which is rotatably disposed inside the slot. A deflector is rotatably mounted on the side wall of the ratchet frame, and a ratchet is mounted at the end of the deflector. The deflector is controlled to rotate by a controller. During operation, when the ratchet frame extends into the slot, the controller drives the deflector to rotate, which in turn drives the ratchet to rotate. This causes the ratchet to engage with the ratchet teeth on the ratchet surface. Thus, the mutual engagement of the ratchet and the ratchet improves the stability of the gate holder and facilitates the braking of the anchor chain.

[0016] Preferably, the shape of the ratchet is adapted to the shape of the slot.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The ship chain catcher of the present invention controls the movement of the telescopic end of the electric push rod on the side wall of the L-shaped support, so that the telescopic end of the electric push rod drives the rectangular block and the locking rod to move until the locking rod engages with the corresponding horizontal chain link gap of the anchor chain. This design can precisely control the gap between the locking rod and the anchor chain. When the anchor chain becomes longer due to stretching or there are differences in the chain link size, it is not necessary to replace the entire device. Only the position of the locking rod needs to be adjusted to regain a tight fit and ensure effective locking.

[0019] 2. The chain stopper for ships described in this invention, when rotating the horizontal shaft to drive the gate holder to rotate towards the side closer to the anchor chain, simultaneously drives the gear at its end to rotate. Since the gear and the toothed plate are meshed, the gear drives the toothed plate to move, which in turn drives the connecting frame to move towards the side closer to the anchor chain. The connecting frame then drives the locking pin to further engage in the gap of the vertical chain link of the anchor chain. This design allows the locking rod to engage the horizontal chain link, while the locking pin can engage the vertical chain link, providing a secondary safety function. This dispersed force reduces the pressure at each contact point, allowing the anchor chain to be braked more smoothly and reliably, reducing the risk of damage to the anchor chain or the chain stopper itself due to stress concentration under huge impact forces.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 8 As shown in the embodiment of the present invention, a ship chain stop includes a hull frame 1. A chain stop base 2 is mounted on the surface of the hull frame 1. A guide wheel 3 is rotatably arranged inside the chain stop base 2. A guide groove 301 is formed on the surface of the guide wheel 3. An anchor chain 4 is arranged on the surface of the guide wheel 3. A fixing frame 5 is mounted above the chain stop base 2. A rotating horizontal shaft 501 is rotatably arranged on the inner side of the fixing frame 5. The end of the rotating horizontal shaft 501 is connected to the output end of a motor. A gate holder 6 is fixedly mounted on the outer circumference of the rotating horizontal shaft 501. A plurality of locking rods 701 are arranged below the gate holder 6. The plurality of locking rods 701 are used to cooperate with the gaps of the horizontal chain links at different positions of the anchor chain 4 and to lock the anchor chain 4.

[0032] During operation, once the anchor is dropped and reaches the predetermined chain length, the anchor winch brake first initially brakes the anchor chain 4. Then, it controls the rotation of the knife block 6, causing the knife block 6 to rotate towards the side closer to the anchor chain 4. This controls the motor to drive the rotating horizontal shaft 501 to rotate, causing the rotating horizontal shaft 501 to drive the knife block 6 and the clamping rod 701 to rotate towards the side closer to the anchor chain 4. Then, the clamping rods 701 at different positions will lock into the gaps of the anchor chain 4 links at different locations, thus braking the anchor chain 4. In this way, compared to the huge tensile force originally borne by a single knife block or clamping block, it is distributed to multiple support points, reducing the load on individual components and improving the overall service life of the chain brake.

[0033] Moreover, when the ship anchors, the weight of the anchor and anchor chain 4, as well as the impact force caused by wind, waves and currents, are enormous. The chain catcher firmly fixes the anchor chain 4 through its robust mechanical structure. This force is then directly transmitted to the reinforced structure of the ship's deck through the base of the chain catcher, thus bypassing the anchor winch, which is precisely manufactured but has limited load-bearing capacity.

[0034] The end of the gate holder 6 away from the horizontal axis of rotation 501 is equipped with a bonding plate 7, and the locking rod 701 is provided on the lower end surface of the bonding plate 7. The lower end surface of the bonding plate 7 is provided with an adjustment unit, which is used to adjust the position of the locking rod 701.

[0035] During operation, when it is necessary to brake the anchor chain 4, the control motor drives the horizontal shaft 501 to rotate. The horizontal shaft 501 drives the gate holder 6 to rotate towards the side closer to the anchor chain 4. Then, the gate holder 6 will drive the bonding plate 7 to press against the surface of the anchor chain 4. Through the action of the adjustment unit, the gap between the clamping rod 701 at different positions and the horizontal chain link of the anchor chain 4 can be adjusted to match each other. The anchor chain 4 is fixed by the clamping rod 701 at different positions. Compared with the huge tensile force originally borne by a single gate or clamping block, it is distributed to multiple support points, reducing the load on individual components.

[0036] The adjustment unit includes an L-shaped support frame 8, an electric push rod 9 is installed on the side wall of the L-shaped support frame 8, a rectangular block 10 is fixedly installed on the telescopic end of the electric push rod 9, the rectangular block 10 is slidably disposed on the lower end surface of the bonding plate 7, and the clamping rod 701 is installed on the lower end surface of the rectangular block 10.

[0037] During operation, when the gate holder 6 rotates towards the side closer to the anchor chain 4 and engages with the horizontal chain link gap of the anchor chain 4, if the locking rod 701 fails to fully engage with the horizontal chain link gap of the anchor chain 4, the telescopic end of the electric push rod 9 on the side wall of the L-shaped support 8 is moved. This telescopic end of the electric push rod 9 drives the rectangular block 10 and the locking rod 701 to move until the locking rod 701 engages with the corresponding horizontal chain link gap of the anchor chain 4. This design allows for precise control of the gap between the locking rod 701 and the anchor chain 4. When the anchor chain 4 becomes longer due to stretching or there are differences in the chain link size, it is not necessary to replace the entire device. Simply adjust the position of the locking rod 701 to regain a tight fit and ensure effective locking.

[0038] An L-shaped support shaft 11 is installed on the lower end face of the rectangular block 10, and the locking rod 701 is rotatably disposed on the inner side of the L-shaped support shaft 11. A circular groove adapted to the locking rod 701 is opened on the surface of the rectangular block 10.

[0039] During operation, when the electric push rod 9 controls the movement of the rectangular block 10 and the locking rod 701, the locking rod 701 can also be rotated on the surface of the L-shaped support shaft 11 to adjust its own angle. This allows the locking rod 701 to better engage in the gaps of different horizontal chain links of the anchor chain 4, making the operation more convenient and facilitating the locking of the anchor chain 4.

[0040] The surface of the bonding plate 7 is provided with a plurality of vertical grooves 12, the upper end face of the rectangular block 10 is provided with a mating groove, and the surface of the bonding plate 7 is provided with a pin 121, which is used to insert into the vertical grooves 12 and penetrate into the mating groove on the upper end face of the rectangular block 10.

[0041] During operation, when the aforementioned locking rod 701 is engaged in the corresponding gap of the anchor chain 4, the rectangular block 10 no longer moves. The operator can insert the pin 121 on the surface of the bonding plate 7 into the mating groove on the upper end face of the rectangular block 10 through the vertical groove 12, thereby fixing the rectangular block 10 and making the rectangular block 10 and the bonding plate 7 a single unit. This allows the impact force of wind and waves on the base of the chain stopper to be directly transmitted to the reinforced structure of the ship's deck, providing a certain degree of protection for the electric push rod 9 and improving its service life.

[0042] A gear 13 is installed at the end of the rotating horizontal shaft 501, and a toothed plate 14 is slidably arranged inside the chain stop base 2. The toothed plate 14 and the gear 13 are meshed and connected. A connecting frame 15 is installed at the end of the toothed plate 14, and a locking post 16 is provided at the end of the connecting frame 15 away from the toothed plate 14.

[0043] During operation, when the horizontal shaft 501 rotates and drives the knife block 6 to rotate closer to the anchor chain 4, the horizontal shaft 501 will simultaneously drive the gear 13 at its end to rotate. Since the gear 13 and the toothed plate 14 are meshed, the gear 13 will drive the toothed plate 14 to move, and the toothed plate 14 will drive the connecting frame 15 to move closer to the anchor chain 4. The connecting frame 15 will drive the locking pin 16 to further lock into the gap of the vertical chain link of the anchor chain 4. With this design, the locking rod 701 can lock the horizontal chain link, and the locking pin 16 can lock the vertical chain link, which plays a secondary safety role. This dispersed force reduces the pressure at each contact point, so that the anchor chain 4 can be braked more smoothly and reliably, reducing the risk of damage to the anchor chain 4 or the chain stopper itself due to stress concentration under huge impact force.

[0044] It should be noted that the same adjustment unit as the aforementioned clamp 701 is provided on the side wall of the connecting frame 15. That is, the function of the clamp 16 is the same as that of the clamp 701, which can adjust the position of the clamp 701 according to the position of the anchor chain 4.

[0045] The chain stop base 2 has a groove inside that matches the toothed plate 14. The diameter of the locking pin 16 is smaller than the length of the gap between the chain links of the anchor chain 4. A connecting support 702 is installed on the upper end face of the gate holder 6. A ratchet 17 is installed on the side of the connecting support 702 away from the gate holder 6. A slot 18 is opened on the surface of the chain stop base 2. A locking unit is provided inside the slot 18. The locking unit is used to cooperate with the ratchet 17 and fix the gate holder 6. During operation, when the gate holder 6 rotates towards the side closer to the anchor chain 4, the gate holder 6 will simultaneously drive the connecting support 702 to rotate. The connecting support 702 will drive the ratchet 17 to move towards the inside of the slot 18. Then, the ratchet 17 will cooperate with the locking unit inside the slot 18, so that the locking unit locks the ratchet 17. This can further improve the stability of the gate holder 6 and ensure high safety.

[0046] The engaging unit includes a ratchet 19, which is rotatably disposed inside the slot 18. A deflector 20 is rotatably mounted on the side wall of the ratchet frame 17, and a ratchet 21 is mounted at the end of the deflector 20. The deflector 20 is controlled to rotate by a controller. The shape of the ratchet frame 17 is adapted to the shape of the slot 18. During operation, when the ratchet frame 17 is inserted into the slot 18, the controller drives the deflector 20 to rotate, which in turn drives the ratchet 21 to rotate. This causes the ratchet 21 to engage with the ratchet teeth on the surface of the ratchet 19. Thus, the mutual engagement of the ratchet 21 and the ratchet 19 improves the stability of the gate holder 6 and facilitates the braking of the anchor chain 4.

[0047] During operation, once the anchor is dropped and reaches the predetermined chain length, the anchor winch brake first initially brakes the anchor chain 4. Then, it controls the rotation of the knife block 6, causing the knife block 6 to rotate towards the side closer to the anchor chain 4. This controls the motor to drive the rotating horizontal shaft 501 to rotate, causing the rotating horizontal shaft 501 to drive the knife block 6 and the clamping rod 701 to rotate towards the side closer to the anchor chain 4. Then, the clamping rods 701 at different positions will lock into the gaps of the anchor chain 4 links at different locations, thus braking the anchor chain 4. In this way, compared to the huge tensile force originally borne by a single knife block or clamping block, it is distributed to multiple support points, reducing the load on individual components and improving the overall service life of the chain brake.

[0048] Moreover, when the ship anchors, the weight of the anchor and anchor chain 4, as well as the impact force caused by wind, waves and currents, are enormous. The chain catcher firmly fixes the anchor chain 4 through its robust mechanical structure. This force is then directly transmitted to the reinforced structure of the ship's deck through the base of the chain catcher, thus bypassing the anchor winch, which is precisely manufactured but has limited load-bearing capacity. When it is necessary to brake the anchor chain 4, the control motor drives the rotating horizontal shaft 501 to rotate. The rotating horizontal shaft 501 drives the gate 6 to rotate towards the side closer to the anchor chain 4. Then, the gate 6 will drive the fitting plate 7 to press against the surface of the anchor chain 4. Through the action of the adjustment unit, the gap between the locking rod 701 at different positions and the horizontal chain link of the anchor chain 4 can be adjusted to cooperate with each other, and the anchor chain 4 can be fixed by the locking rod 701 at different positions.

[0049] When the gate holder 6 rotates towards the side closer to the anchor chain 4 and engages with the horizontal chain link gap of the anchor chain 4, if the locking rod 701 fails to fully engage with the horizontal chain link gap of the anchor chain 4, the telescopic end of the electric push rod 9 on the side wall of the L-shaped support 8 is moved. This causes the telescopic end of the electric push rod 9 to move the rectangular block 10 and the locking rod 701 until the locking rod 701 engages with the corresponding horizontal chain link gap of the anchor chain 4. This design allows for precise control of the gap between the locking rod 701 and the anchor chain 4. When the anchor chain 4... When the chain becomes longer due to stretching or when there are differences in the size of the chain links, it is not necessary to replace the entire device. Simply adjust the position of the locking rod 701 to regain a tight fit and ensure effective locking. When the electric push rod 9 controls the movement of the rectangular block 10 and the locking rod 701, the angle of the locking rod 701 can also be adjusted by controlling the rotation of the locking rod 701 on the surface of the L-shaped support shaft 11. This allows the locking rod 701 to better engage in the gaps of different horizontal chain links of the anchor chain 4, making the operation more convenient and facilitating the locking of the anchor chain 4.

[0050] When the aforementioned locking rod 701 is engaged in the corresponding gap of the anchor chain 4, the rectangular block 10 no longer moves. The worker can then insert the pin 121 on the surface of the bonding plate 7 through the vertical slot 12 into the mating slot on the upper surface of the rectangular block 10, thus fixing the rectangular block 10 and making it an integral unit with the bonding plate 7. This allows the impact force of wind and waves on the chain catcher's base to be directly transmitted to the reinforced structure of the ship's deck, providing a certain degree of protection for the electric push rod 9 and improving its service life. When rotating the horizontal shaft 501 drives the gate holder 6 to rotate towards the side closer to the anchor chain 4, rotating the horizontal shaft 501 will simultaneously drive its end... When gear 13 rotates, it will drive gear 14 to move due to the meshing connection between gear 13 and toothed plate 14. This will cause gear 13 to drive connecting frame 15 to move closer to anchor chain 4. Connecting frame 15 will drive locking pin 16 to further lock into the vertical chain link gap of anchor chain 4. With this design, locking rod 701 can lock the horizontal chain link, while locking pin 16 can lock the vertical chain link, playing a secondary safety role. This dispersed force reduces the pressure at each contact point, allowing anchor chain 4 to be braked more smoothly and reliably, reducing the risk of anchor chain 4 or chain brake itself being damaged due to stress concentration under huge impact force.

[0051] When the gate holder 6 rotates towards the side closer to the anchor chain 4, the gate holder 6 will simultaneously drive the connecting support 702 to rotate. The connecting support 702 will drive the ratchet 17 to move closer to the inside of the slot 18. Then the ratchet 17 will cooperate with the engaging unit inside the slot 18, so that the engaging unit locks the ratchet 17. This can further improve the stability of the gate holder 6 and increase safety. When the ratchet 17 is deep into the slot 18, the controller drives the deflection rod 20 to rotate. The deflection rod 20 drives the ratchet 21 to rotate, so that the ratchet 21 is locked on the ratchet teeth on the surface of the ratchet wheel 19. In this way, the mutual engagement of the ratchet 21 and the ratchet wheel 19 improves the stability of the gate holder 6 and is beneficial for braking the anchor chain 4.
